A Practical Approach to Rheology

This series of four webinars is designed to educate the user on the basics of measurement, calibration, maintenance, experimental design, and theory & applications, as it relates to rheology. Each webinar is about 60 minutes long, and will have a 10-minute question and answer session at the end. A Certificate of Completion will be awarded to viewers who watch all 4 webinars in this series.

Introduction to Rheology

Episode 1 of this four part series will establish a framework for understanding rheology, addressing four fundamental topics.

Viscosity Measurements on Liquids

Yield and Thixotropy Measurements

Beyond viscous behavior, complex fluids can exhibit other important flow characteristics, most notably yield stresses and thixotropy. In this third part, we will explore effective ways to quantify these behaviors.

Quantifying Viscoelasticity

About The Speakers

Nathan D. Hesse, Ph.D. is a Senior Applications Scientist who joined TA Instruments in 2005 and currently supports the Rheology product line based out of the company headquarters in New Castle, DE. He earned his Ph.D. in Analytical Chemistry from the University of Oklahoma in 2002 where his focus was species specific characterization and kinetics of catalytic polymer decomposition. Prior to joining TA, he worked for Thermometric, which has since been added to the TA Instruments Microcalorimetry portfolio. With over 15 years of collective experience, Nathan has provided technical application and instrument support throughout the TA organization and most importantly to our customers using the Thermal Analysis, Microcalorimetry, and Rheology product lines.

Tianhong (Terri) Chen, Ph.D. is a Senior Applications Support Scientist with TA Instruments currently supporting the Rheology and DMA product lines. She received her PhD degree in Polymer Science from Sun Yat-sen University (SYSU) in China, specializing in polymer synthesis and characterization. She did her post-doc research and later became a research assistant professor at the University of Maryland. During that time, her research was focused on biopolymer modifications and analysis. Dr. Chen joined TA Instruments in 2004. Her key responsibilities at TA Instruments are customer support, consultation, and teaching DMA and rheology training courses. Dr. Chen has more than 50 publications in peer-reviewed journals and two US patents.
